Description
TECHNICAL FIELD
[0001] The present application claims priority to and the benefits
of Korean Patent Application No. 10-2016-0085746, filed with the
Korean Intellectual Property Office on Jul. 6, 2016, the entire
contents of which are incorporated herein by reference.
[0002] The present application relates to a hetero-cyclic compound
and an organic light emitting device using the same.
BACKGROUND ART
[0003] An electroluminescent device is one type of self-emissive
display devices, and has an advantage of having a wide viewing
angle, and a high response speed as well as having an excellent
contrast.
[0004] An organic light emitting device has a structure disposing
an organic thin film between two electrodes. When a voltage is
applied to an organic light emitting device having such a
structure, electrons and holes injected from the two electrodes
bind and pair in the organic thin film, and light emits as these
annihilate. The organic thin film may be formed in a single layer
or a multilayer as necessary.
[0005] A material of the organic thin film may have a light
emitting function as necessary. For example, as a material of the
organic thin film, compounds capable of forming a light emitting
layer themselves may be used alone, or compounds capable of
performing a role of a host or a dopant of a host-dopant-based
light emitting layer may also be used. In addition thereto,
compounds capable of performing roles of hole injection, hole
transfer, electron blocking, hole blocking, electron transfer,
electron injection and the like may also be used as a material of
the organic thin film.
[0006] Development of an organic thin film material has been
continuously required for enhancing performance, lifespan or
efficiency of an organic light emitting device.

EXPERIMENTAL EXAMPLE
Experimental Example 1
[0171] 1) Manufacture of Organic Light Emitting Device
[0172] A glass substrate on which ITO was coated as a thin film to
a thickness of 1500 .ANG. was cleaned with distilled water and
ultrasonic waves. After the cleaning with distilled water was
finished, the substrate was ultrasonic cleaned with solvents such
as acetone, methanol and isopropyl alcohol, then dried, and UVO
treatment was carried out for 5 minutes in a UV cleaner using UV.
After that, the substrate was transferred to a plasma cleaner (PT),
and plasma treatment was carried out under vacuum for removing ITO
work function and remaining film, and the substrate was transferred
to a thermal deposition apparatus for organic deposition.
[0173] On the ITO transparent electrode (anode), organic materials
were formed in a two-stack white organic light emitting diode
(WOLED) structure. As for the first stack, a hole transfer layer
was formed first by thermal vacuum depositing TAPC to a thickness
of 300 .ANG.. After forming the hole transfer layer, a light
emitting layer was thermal vacuum deposited thereon as follows. The
light emitting layer was deposited to 300 .ANG. by doping FIrpic in
8% as a blue phosphorescent dopant to TCzl, a host. An electron
transfer layer was formed to 400 .ANG. using TmPyPB, and then a
charge generation layer was formed to 100 .ANG. by doping
Cs.sub.2CO.sub.3 in 20% to a compound described in the following
Table 9.
[0174] As for the second stack, a hole injection layer was formed
first by thermal vacuum depositing MoO.sub.3 to a thickness of 50
.ANG.. A hole transfer layer, a common layer, was formed by doping
MoO.sub.3 to TAPC in 20% and forming to 100 .ANG., and then
depositing TAPC to 300 .ANG.. After depositing a light emitting
layer to 300 .ANG. thereon by doping Ir(ppy).sub.3, a green
phosphorescent dopant, in 8% to TCzl, a host, an electron transfer
layer was formed to 600 .ANG. using TmPyPB. Lastly, an electron
injection layer was formed on the electron transfer layer by
depositing lithium fluoride (LiF) to a thickness of 10 .ANG., and
then a cathode was formed on the electron injection layer by
depositing an aluminum (Al) cathode to a thickness of 1,200 .ANG.
to manufacture an organic electroluminescent device.
[0175] Meanwhile, all the organic compounds required to manufacture
the OLED device were vacuum sublimation purified under 10.sup.-6
torr to 10.sup.-8 torr by each material to be used in the OLED
manufacture.

[0176] 2) Driving Voltage and Light Emission Efficiency of Organic
Electroluminescent Device
[0177] For the organic electroluminescent devices manufactured as
above, electroluminescent light emission (EL) characteristics were
measured using M7000 manufactured by McScience Inc., and with the
measurement results, T95 when standard luminance was 3,500
cd/m.sup.2 was measured using a lifetime test system (M6000)
manufactured by McScience Inc. Results of measuring a driving
voltage, light emission efficiency, external quantum efficiency and
a color coordinate (CIE) of the white organic electroluminescent
devices manufactured according to the present disclosure are as
shown in Table 9.

[0178] As shown from the results of Table 9, the organic
electroluminescent devices using the charge generation layer
material of the 2-stack white organic electroluminescent device of
the present disclosure had a low driving voltage and improved light
emission efficiency compared to Comparative Examples 1-1, 1-2, 1-3,
1-4 and 1-5. Particularly, it was identified that Compounds 62, 63,
95, 207, 210, 217, 226, 228, 230, 247, 260 and 261 were
significantly excellent in all of driving, efficiency and
lifespan.
[0179] The presumed reason for such results is that the compound of
the present disclosure used as an N-type charge generation layer
formed with an invented skeleton having proper length, strength and
flat property and a proper hetero-compound capable of binding with
metals is doped with an alkali metal or an alkali-earth metal to
form a gap state within the N-type charge generation layer, and
electrons produced from a P-type charge generation layer are
readily injected to the electron transfer layer through the gap
state produced within the N-type charge generation layer.
Accordingly, the P-type charge generation layer favorably carried
out electron injection and electron transfer to the N-type charge
generation layer, and as a result, it is considered that a driving
voltage of the organic light emitting device decreased, and
efficiency and lifespan were improved.
Experimental Example 2
[0180] 1) Manufacture of Organic Light Emitting Device
[0181] A glass substrate on which ITO was coated as a thin film to
a thickness of 1500 .ANG. was cleaned with distilled water and
ultrasonic waves. After the cleaning with distilled water was
finished, the substrate was ultrasonic cleaned with solvents such
as acetone, methanol and isopropyl alcohol, then dried, and UVO
treatment was carried out for 5 minutes in a UV cleaner using UV.
After that, the substrate was transferred to a plasma cleaner (PT),
and plasma treatment was carried out under vacuum for removing ITO
work function and remaining film, and the substrate was transferred
to a thermal deposition apparatus for organic deposition. On the
ITO transparent electrode (anode), organic materials were formed in
a single-stack structure. As a hole injection layer, HAT-CN was
deposited to a thickness of 50 .ANG., and subsequently, a hole
transfer layer was formed by doping DNTPD within 10% to NPD,
depositing the result to a thickness of 1500 .ANG., and
continuously depositing TCTA to a thickness of 200 .ANG..
Subsequently, a light emitting layer comprising a t-Bu-perylene
dopant in an ADN host was formed to a thickness of 250 .ANG.. Next,
Alq.sub.3, an electron transfer layer, was formed to a thickness of
250 .ANG., and an N-type charge transfer layer was formed to a
thickness of 100 .ANG. by doping Li, an alkali metal, to a compound
described in the following Table 10, and Al, a cathode, was formed
to a thickness of approximately 1,000 .ANG. to manufacture an
organic electroluminescent device.

Experimental Example 3
[0186] 1) Manufacture of Organic Light Emitting Device
[0187] A transparent electrode ITO thin film obtained from glass
for an OLED (manufactured by Samsung Corning Advanced Glass) was
ultrasonic cleaned consecutively using trichloroethylene, acetone,
ethanol and distilled water for 5 minutes each, placed in
isopropanol and stored, and then used.
[0188] Next, the ITO substrate was installed in a substrate folder
of vacuum deposition equipment, and the following
4,4',4''-tris(N,N-(2-naphthyl)-phenylamino)triphenyl amine
(2-TNATA) was introduced to a cell in the vacuum deposition
equipment.
##STR00125##
[0189] Subsequently, the chamber was exhausted until the degree of
vacuum inside the chamber reached 10.sup.-6 torr, and then a
current was applied to the cell to evaporate the 2-TNATA to deposit
a hole injection layer having a thickness of 600 .ANG. on the ITO
substrate.
[0190] The following
N,N'-bis(.alpha.-naphthyl)-N,N'-diphenyl-4,4'-diamine (NPB) was
introduced to a different cell in the vacuum deposition equipment,
a current was applied to the cell to evaporate to deposit a hole
transfer layer having a thickness of 300 .ANG. on the hole
injection layer.
##STR00126##
[0191] After forming the hole injection layer and the hole transfer
layer as above, a blue light emitting material having a structure
as follows was deposited thereon as a light emitting layer.
Specifically, H1, a blue light emitting host material, was vacuum
deposited to a thickness of 200 .ANG. on one cell in the vacuum
deposition equipment, and D1, a blue light emitting dopant
material, was vacuum deposited thereon in 5% with respect to the
host material.
##STR00127##
[0192] Subsequently, compounds of the following structural formulae
E1, N-ADN2, N-ADN5, N-AN9 and N-AN11 were deposited to a thickness
of 300 .ANG. as an electron transfer layer.
##STR00128## ##STR00129##
[0193] As an electron injection layer, lithium fluoride (LiF) was
deposited to a thickness of 10 .ANG., and an Al cathode was formed
to a thickness of 1000 .ANG. to manufacture an OLED device.
[0194] Meanwhile, all the organic compounds required to manufacture
the OLED device were vacuum sublimation purified under 10.sup.-6
torr to 10.sup.-8 torr by each material to be used in the OLED
manufacture.

measurement results, Tss when standard luminance was 700 cd/m.sup.2
was measured using a lifetime test system (M6000) manufactured by

[0197] As shown from the results of Table 11, the organic
electroluminescent devices using the electron transfer layer
material of the blue organic electroluminescent device of the
present disclosure had a low driving voltage and significantly
improved light emission efficiency and lifespan compared to
Comparative Examples 3-1, 3-2, 3-3, 3-4 and 3-5. Particularly, it
was identified that Compounds 3, 5, 7, 41, 45, 46, 91, 93, 138,
142, 147, 148, 164, 192, 193 and 203 were significantly excellent
in all of driving, efficiency and lifespan.
[0198] The presumed reason for such results is that, when the
invented compound having proper length, strength and flat property
is used as an electron transfer layer, a compound in an excited
state is produced by receiving electrons under a specific
condition, and particularly, when the excited state is formed in
the heteroskeleton site of the compound, excited energy moves to a
stable state before the excited heteroskeleton site goes through a
different reaction, and the relatively stabilized compound is
capable of efficiently transferring electrons without compound
decomposition or destruction. As a reference, it is considered that
those having a stable state when excited are aryl or acene series
compounds or multicyclic hetero-compounds. Accordingly, it is
considered that the compound of the present disclosure enhances
electron-transport properties or improved stability resulting in
excellency in all of driving, efficiency and lifespan.
